Abstract: ABSTRACT           "A method and apparatus for the coded tagging of articles, particularly garments"     A method for the coded tagging of articles, such as garments, comprises fitting to each of a plurality of articles a tagging element bearing coded information in the form of portions of the element, such as holes therein, which permit the passage therethrough of a form of radiation to which the rest of the element is opaque.  Articles bearing the tagging elements are then passed in succession between an emitter and a detector of said form of radiation, and signals from the detector are electronically processed to produce an output corresponding to the coded information on each tagging element.

Abstract: ABSTRACT        Apparatus is disclosed for determining the degree of stiffness of a sheet, for example a banknote, the stiffness being indicative of the condition of the banknote.  The banknote (4) is drawn around a bobbin-shaped drum (1) by means of a pair of belts (2, 3) which grip a central portion of the banknote.  The inner belt (2) drives or is driven by the central portion of the drum (1).  The concave shape of the drum (1) imparts a curvature to the banknote in an axial plane, while the banknote is simultaneously curved in an orthogonal plane as it is wrapped around the drum.  As the banknote passes around the drum it emits an audible noise which is picked up by a microphone (5).  The amplitude of the microphone signal (7) is proportional to the crispness of the banknote and is indicative of the age of the banknote.

Abstract: 49,771 ABSTRACT OF THE DISCLOSURE A capacitor unit including a capacitive element connected in parallel with a discharge resistor is provid-ed with a switch in series with the resistor.  This switch responds to power frequency current flowing through the capacitive element such that it opens to remove the dis-charge  resistor  from the  circuit when power  frequency current is flowing through the capacitor unit and closes when power frequency current stops,  thus reinserting the discharge resistor to eliminate any residual charge re-maining on the capacitive element.

Abstract: ABSTRACT OF THE DISCLOSURE         An earth boring machine is shown with an improved kelly seal.  The machine includes a hydraulic cylinder and a kelly rotatably carried within the cylinder and axially cylinder.  A rotary quill surrounds the kelly for supplying rotational force within the hydraulic cylinder proximate and end thereof seals hydraulic fluid within the hydraulic cylinder.  An improved retaining assembly connects the relative rotational movement of the packing assembly with respect to the rotary quill about the longitudinal axis of the kelly.  The limited movement provided by the retainer assembly isolates the packing assembly from drive torque which is transferred from the rotary quill to the kelly, thereby reducing the tendency of the packing assembly to drive the kelly.

Abstract: ABSTRACT         Fractionation apparatus is disclosed which utilizes a rapidly rotating disk which receives a liquid suspension of particles to be separated onto its rotating face surface.  When the film of liquid and particles on the rotating face surface reaches the peripheral edge of the face, particles above a certain size are radially ejected while smaller particles and the liquid are carried over the edge onto the surface of a depending rim.  The suspension of smaller particles and liquid is carried down the rim to the rim edge at which point the smaller particles and liquid are disengaged.  A separator wall may be interposed between the two streams of particles emanating from the disk to provide a physical separation of the larger and smaller particles once they have left the disk.  The characteristics of the face surface, the angle of the rim with respect to the face, the disk speed, suspension feed rate, and other operating conditions can be selected such that highly efficient fractionations of particle suspensions, such as wood pulp slurries, can be obtained about a selected break point particle size.

Abstract: ABSTRACT           A disc camera advances a film disc by an oscillating pawl engaging the disc film notches previously used for indexing.  The pawl is carried on a member pivotably mounted on the side of the rear film chamber wall remote from the chamber and passing through an opening in this wall.  The limits of movement of this member are determined by the height of a lobe of a rotating cam driving the pawl system and by other mechanical limit stops.  An end-of-film sensing pin is provided which passes through the rear film chamber wall of the camera and engages the face of the film disc hub directly.  When the pin drops into the film disc hub, the film advance motor circuit is rendered inoperative.  A single printed circuit board placed near and parallel to the side of the film chamber wall remote from the film chamber carries the DC motor, shutter-cocking and the pawl-oscillating mechanism.  The pawl carrying member is pivoted on this wall.  A film flattening shroud frame on the rear chamber wall has only its tangentially disposed faces or edges contacting the film disc so that the other two margins thereof do not contact the portion of the film to be exposed during film advancement.

Abstract: TITLE                             DUCT JOINT FRAME     ABSTRACT OF THE DISCLOSURE         A plurality of flange members are positioned oppositely of one another on the ends of a pair of generally rectangular sheet metal ducts.          The flange members are positioned in pairs on the adjacent ends of the ducts.   The angular legs of corner pieces extend into the ends of the flange members to connect the adjacent flange members on the end of each duct so that four corner pieces connect the flange members to form a frame around the respective duct end portion.  The oppositely positioned flange members on the adjacent duct end portions are sealingly secured together by clamping together the adjacent corner pieces.   Each flange member is formed by a thin walled sheet member and includes a pair of legs angularly disposed relative to one another to form a plurality of wall sections.  A first wall section terminates in a first leg end portion, and a second wall section terminates in a second leg end portion.  The first and second leg end portions are spaced apart.  The first and second wall sections are positioned in overlying relation to receive the duct end portion there-between.   The duct end portion overlies the second wall section which extends around and below the duct end portion to a stop on the second leg end portion.  The stop engages a plurality of protuberances or dimples on the surface of the duct adjacent the duct end portion to prevent retrac-tion of the duct end portion from the flange member.  The first leg end portion forms an abutment shoulder, and the duct end portion engages the abutment shoulder.  Thus, the duct is rigidly secured between the stop and the abutment shoulder, thereby, eliminating freedom of movement between the flange wall sections to provide a torsionally rigid connection of each flange member to the duct end portion that resists bending of adjacent flange members away from each other to prevent air leakage at the duct joint.

Abstract: ABSTRACT     The  invention pertains  to  a method  and  device  for testing the permeability of membrane filters by submitting a wetted membrane filter on its inlet side to a predetermined testing gas pressure within a first closed system and by measuring pressure variation over time within the closed system.   The object of the method of the invention is a sensitive testing method permitting permeability, and thus pore size, of a membrane filter to be determined exclusively by measurements performed on the inlet side of the membrane filter.    Such measurement  is  performed  by  measuring  a pressure differential with respect to a reference pressure, or by measuring the quantity of gas per unit of time flowing with respect to a  reference pressure system,  or else by measuring  the pressure  differential  twice  and  draining, during the second measurement, a predetermined quantity of gas from the space being tested.
